<li>Click "Browse".</li>
<li>Browse for a REDCAT file.</li>
<li>Input to REDCAT consists of nine space delimited columns of data for every RDC entry.  The nine columns are:  x, y, and z coordinates of the first atom; x, y, and z coordinates of the second atom; experimental RDC, maximum RDC for that vector type at 1 Angstrom distance; and measurement error.
<li>In preparing your input file, please ensure that the following criteria are met:</li>
<ol type="a">
<li>There should be no leading spaces in the input files.</li>
<li>Each datum in the input file needs to be separated by only one delimiter.  Do not put multiple spaces or tabs in the input file to make it esthetically pleasing to the eye.</li>
<li>There should be no blank lines at the beginning, in the middle, or at the end of the input file.</li>
<li>A RDC value of 999 is interpreted as a missing value and will automatically be excluded from all analyses.</li></ol>
<li>Click "Upload".</li>
<li>Data from the file will be displayed on the screen in tabular format.</li>
<li>Once you have uploaded the file, you can proceed with either Run, Error Analysis, or Calculate RDCs</li>
</ol>
